Following on from the previous two of these threads both with 6% mortgage rates in the title, I think it's more realistic to return to 5% for this one.
According to this Rightmove article, the current average mortgage rate for a five-year fixed rate mortgage is 4.84%, up from 4.85% last week. The current average rate for a two-year fixed rate mortgage is 5.23%, which is unchanged from last week. The lowest available five-year fixed rate is 4.13%, and the lowest available two-year fixed rate is 4.46% – both unchanged from last week.
On 27th March, the average 5 year fixed rate mortgage for someone with a 60% LTV was 4.35%.
For someone with a 75% LTV it was 4.72% whereas 80% was 4.79%.
For someone with a 90% LTV it was 4.98% whereas 95% was 5.47%.
Two year fixed rate mortgages are slightly higher.
